The username input field has a type="textbox" attribute what makes Firefox not recognize the field as part of a login form.
You can use this bookmarklet to change the type to type="text".
You can create a new bookmark on the Bookmarks Toolbar and paste the JavaScript code in its URL field where you would normally enter the address of the website.
javascript:/*LOGIN:fix-type username*/(function(){ var I=1,T,Z=0; var A=document.activeElement,E; if(A.nodeName.toLowerCase()=='input'){ T=A.getAttribute('type'); if((T!='text')&&(T!='password')){A.setAttribute('type','text');Z=1} if(I){alert('input: '+['<'+T+'>','<fixed-type>'][Z])} } })()
You can click in the username field to set focus to this field and then click the above created bookmark to invoke the JavaScript code.
You should see a message that the input field has been fixed and you should see "Use Saved Password" in the right-click context menu.
You can edit this login in the Password Manager (about:logins) and enter the correct username and password.
